Auxiliary Envelopes
The Pro 3 has two additional 5-stage envelope generators (attack, decay,
sustain, release, plus delay). They are useful for creating modulation
that varies over time according to the shape of the envelope. Routing an
envelope to an oscillator’s frequency, for example, causes the oscillator’s
pitch to rise and fall according to the contour of the envelope.
As with all of the Pro 3’s envelopes, there are controls for modulating the
envelope amount using keyboard velocity. The Auxiliary Envelopes can be
routed to any of the modulation destinations in the mod matrix. In addition,
the Auxiliary Envelopes can repeat (loop) using the
repeat
function in the
aux envelopes display menu. This is useful for cyclical 4-stage modulation.
There are many ways to make creative use of the Auxiliary Envelopes:
• Route an Auxiliary Envelope to one of the oscillators’
coarse freq
parameter to create the classic “pitch blip” effect used in many synth
lead sounds.
• Route an Auxiliary Envelope to the filter’s
cutoff
parameter (in addi-
tion to the standard Filter Envelope) to create a more complex filter
envelope shape.
• Route an Auxiliary Envelope to one or more of the oscillators’
shape
parameter to make their timbre evolve according to envelope’s contour.
• Route an Auxiliary Envelope with a fast attack and short decay to
noise
level
to add a percussive attack to a sound. (Noise should be set to zero
in the Mixer.)
Actually, any of the Pro 3’s envelopes can be routed to any destination (or multiple
destinations) using the modulation matrix. See “Modulation” on page 47 for more
information.
